Help: Friend's AR having FTExtract

[Harry Tuttle]

The D ring is a band aid on a sprained ankle
you should not need to super charge the extractor to get proper function on a civilian semi AR15

i would suspect ammunition, lubrication, extractor spring, gas port sizing, or the chamber

Yer not kiddin'. Heeding the advice from you fine folks, we took the gun apart to see whether it was stamped .223 Rem or 5.56 NATO. Checked the upper in and out, and checked the barrel everywhere, even under the handguards...

Guess what? It isn't stamped for caliber ANYWHERE. I've told him to try to get a RRA upper... what do you think?

So we went out again tonight. I had him fire a few rounds of the stuff that has the malfs, and they all show that the extractor just wasn't getting into the rim.

We took a box of other generic stuff (NATO stamped) that he'd gotten at a sporting goods store in town, and it all worked perfectly.

I forgot to get one of his casings from the bad stuff, so that maybe someone could help me see what it all means... I'll try to get it tomorrow.

It seems that the ammo was the problem. (All mags worked with good ammo, jammed with bad ammo BTW).

Thanks for your help, guys. I'll post the headstamp later.

Another thing to check is the gas rings. If the gaps in the three rings are lined up it will fail to fully extract believe it or not. If they are lined up space the gaps roughly evenly around the bolt. I agree with another poster in another thread, stoner was just that, a stoner.
